EPA Launches New Tool to Support Community Interest in Green Infrastructure

EPA is releasing a new web-based tool that helps local officials and other community members consider the benefits and uses of green infrastructure.  The Green Infrastructure Wizard, or GIWiz, responds to growing community interest in using green infrastructure as a means of addressing water quality and a range of other local goals.  Using a self-guided format, users can find EPA tools and resources to:

  • Learn the basics of green infrastructure;
  • Explore options for financing green infrastructure;
  • Visualize and design rain gardens, permeable pavement, and other types of green infrastructure;
  • Understand how other communities are using green infrastructure to revitalize neighborhoods and enhance land use; and
  • Develop green infrastructure public education and outreach campaigns.

EPA developed the Green Infrastructure Wizard with input from local, state and tribal partners. EPA is inviting additional input on this Beta version of the product, with the goal of making continued improvements going forward.

San Diego Low Impact Design Manual available

The 2011 San Diego (CA) Low Impact Design Manual is now available under the Resources/Informational Publications tabs. The Manual is an excellent resource for low impact development and green infrastructure designs in urban environments. Many thanks to Dr. Michael Marcus, Tetra Tech (Ret.) for this document.

EPA Releases New Report on Case Studies Analyzing the Economic Benefits of Low Impact Development and Green Infrastructure

EPA recently released a new technical report called “Case Studies Analyzing the Economic Benefits of Low Impact Development and Green Infrastructure” that helps utilities, state and other municipal agencies, and other stormwater professionals understand the  potential benefits of low impact development and green infrastructure (LID/GI) programs. The objective of the report is to highlight different evaluation methods that have been successfully applied and also to demonstrate cases where LID/GI projects and programs have been shown to be economically beneficial. Also, the intent of this document is to promote the use of LID/GI, where appropriate, to supplement grey stormwater infrastructure.

The report highlights 13 case studies of selected public entities throughout the United States that have conducted economic evaluations of their LID/GI programs. The case studies were selected to represent a variety of analysis methods in different geographic areas of the United States, for different types of municipal programs. The case studies highlight locations where LID/GI applications, in combination with grey infrastructure, were found to be economically beneficial.

Stormwater professionals can use the information and resources provided in this report when planning, implementing, and assessing their own LID/GI programs. The report provides a starting framework that both illustrates how others have evaluated the costs and benefits of their LID/GI projects and programs, and suggests methods communities may want to investigate to get  started on their own community specific analyses.

The 142-page technical report is available on EPA’s Low Impact Development website at www.epa.gov/nps/lid.

EPA Releases New Green Infrastructure Strategy, Focuses on Making Green Infrastructure a Part of Business as Usual for Communities

EPA has launched a new strategy to expand the use of green infrastructure, with the goal of making green infrastructure a part of business as usual for local communities. The Agency’s 2013 Green Infrastructure Strategy builds on its previous 2008 and 2011 green infrastructure strategies. The new strategy maintains a focus on information exchange and community engagement, while focusing on improving federal coordination, Clean Water Act regulatory support, research and information exchange, funding and financing, and capacity building.

EPA’s National Stormwater Calculator is Now Available to the Public

 

http://www.epa.gov/nrmrl/wswrd/wq/models/swc/

EPA’s National Stormwater Calculator is a desktop application that estimates the annual amount of rainwater and frequency of runoff from a specific site anywhere in the United States. Estimates are based on local soil conditions, land cover, and historic rainfall records.

It is designed to be used by anyone interested in reducing runoff from a property, including

  • ·         site developers,
  • ·         landscape architects,
  • ·         urban planners, and
  • ·         homeowners.

The Calculator accesses several national databases that provide soil, topography, rainfall, and evaporation information for the chosen site. The user supplies information about the site’s land cover and selects the types of low impact development (LID) controls they would like to use.  The LID controls that the user can choose are seven green infrastructure practices:

1.    Disconnection

2.    Rain harvesting

3.    Rain gardens

4.    Green roofs

5.    Street planters

6.    Infiltration basins

7.    Porous pavement

Green infrastructure promotes the natural movement of water, instead of allowing it to wash into streets and down storm drains. Green infrastructure also has the added benefit of beautifying neighborhoods and increasing property values.

The stormwater calculator (SWC), like any model, estimates an outcome based on available information such as soil type, landscape and land-use information, and historical weather. These estimates can be affected by limitations on site-specific information and uncertainties about future climate. To better inform decisions, it is recommended that the user develop a range of results with various assumptions about model inputs such as percent of impervious surface, soil type, and sizing of green infrastructure. An update to the SWC, which will include the ability to link to several future climate scenarios, will be released by the end of 2013. Climate projections indicate that heavy precipitation events are very likely to become more frequent as the climate changes. Green Infrastructure can increase the resiliency of stormwater management approaches to a changing climate, and this update will allow users to consider how runoff may vary based both on historical weather and potential future climate. Please check with local authorities about whether and how use of these tools may support local stormwater management goals and requirements.

Clean water is essential to keeping our families and the environment healthy. The Calculator helps protect and restore the environmental integrity of our waterways.

EPA Features Locally Led Efforts in Urban Water Restoration via Video Series

 

Urban Waters Voices: Darryl Haddock
Urban Waters Voices: Darryl Haddock

EPA has released Urban Waters Voices, a series of 12 video interviews featuring locally led efforts to restore urban waters in communities across the United States. These videos feature local efforts and strategies to improve urban water quality while advancing local community priorities. This week’s video spotlights Darryl Haddock, Environmental Education Director for the West Atlanta Watershed Alliance, describing some of the challenges faced by communities in the watersheds of Proctor, Sandy, and Utoy Creek (e.g. combined sewer overflows, water quality issues, and access to recreational opportunities) and how the organization is using their outdoor activity center to educate and engage residents about these challenges. Watch the video.
